3 Claims.

My present invention relates to improvements in dispensers adapted to beused for dispensing liquids, essences and powders of various kinds andmore particularly relates to that class of dispenser shown and describedin the patent to McAtree, No. 1,731,250, dated October 15, 1929 andbelonging to the assignee of this application.

It is the purpose of the invention to improve upon the type of dispenserreferred to, by employing an improved form of closure plug which willreadily open-and close the outlet more or less according to the extentof the operation, further to provide guide means whereby the closureplug will be properly maintained at all times in alignment with thedischarge outlet; to provide a cap with an integral annular shoulder anda guide member for the stem of the plug which can readily be positionedin the cap upon the shoulder to form not only a guide for the stem but asupport for the spring which actuates the plug.

It is a further object of the invention to provide a simple andefficient form of dispenser including a valve for the purpose specifiedwhich is positive in operation and will cause desired quantities ofliquid or powder to be discharged at each operation, the quantities sodischarged depending upon the extent and duration of the operation. Thedispenser also is designed to form a closure for the bottle or containerto which it is attached, and in its design represents a simplifiedstructure which can obviously be manufactured sufficiently cheap towarrant its extensive use upon toilet articles to be sold at popularprices. The invention, therefore, consists in the construction andinter-relations and association of parts hereinafter described and moreparticularly pointed out in the claims as will more readily beunderstood by reference to the accompanying drawing, forming a part ofthis specification, and in which Fig. 1 shows a bottle in an invertedposition and provided with my improved combined stopper and dispenser;

Fig. 2 shows a sectional view on a slightly enlarged scale, of the samecombined stopper and dispenser in a closed position and applied to theneck of a bottle in an upright position;

Fig. 3 shows a sectional view of the dispenser in an inverted and openposition, the bottle being omitted and Fig. 4 shows a detached plan viewof a perforated sheet metal spider that serves as a guide for the shankportion of the plunger.

Referring in detail to the characters of refererence marked upon thedrawing Ill indicates a container which in the present instance is inthe form of a bottle, It the neck portion of the bottle and I2 annularscrew threads formed on the peripheral end portion of said neck. The 5threads obviously form a, convenient means for the attachment of thedispenser which is also provided with threads to engage those of thebottle. This form of attaching the dispenser to the container, however,is not essential since other means may be employed without in any wayaffecting the objects. of the. invention.

Referring more specifically to the dispenser proper l3 represents thecap which as shown is made of sheet metal'and cylindrical in formineluding a lower relatively large base portion l4 having internalthreads l5 for engaging the threads I2 in the neck of the container andan upper smaller cylindrical portion l6 formed integral with the lowerlarger diameter and further includes a rounded or dome-like top end I1having a central opening l8 therethrough to receive the conical shapedclosure plug l9.

The shell l3 further includes an internal annular shoulder which may beformed integral with the cap in any suitable manner and comprises a seatupon which the spider 2| rests. This spider is preferably of the shapeand formed as shown in Fig. 4 having a central hole 22 therethrough andradially extended arms 23 which being formed of sheet metal will readilysnap over the annular shoulder when assembling the parts and thus servesto form a bottom rest or support for a spiral spring 24 mounted upon it.The upper and smaller portion of the spring 24 is seated against theannular shoulder 25 of the plug in a way to normally hold it against itsseat but is adapted to readily move away when pressure is applied to theexposed end of the plug.

The plug I9 is mounted within the cap and is adapted to be operatedcentral therein and longitudinally with respect to the neck of thebottle. This plug includes a relatively large conical end portion whichin part extends through the open- 5 ing I8 and is normally positionedagainst the inner edge of said opening and further includes a dependingrelatively smaller shank portion 26 which is reciprocatively mounted inthe before mentioned guide hole 22 of the spider and has an 5 annularshoulder 25 formed beneath the head portion.

The mounting of the plug in the spider in combination with the specialform of spring employed insures a relatively central longitudinalmovement of the plug in a way to form an annular opening around the plugwhen the same is pressed inwardly, an inward pressure forming a variableannular opening depending upon the amount of pressure exerted on theouter end of the plug leaving the contents of the container free to flowor sift through the openings formed between the arms 23, of the spider,the spring and the annular opening around the plug.

Having thus described my invention what I claim and desire to secure byLetters Patent is;

1. A dispenser comprising a closure cap having an orifice therein, .atapered closure plug mounted in the cap and projecting through theorifice and having a rounded end portion and a central depending guidestem of smaller diameter than the plug forming an annular shoulderbeneath the plug, a spider secured in the cap and forming a support withopenings therein and a central hole therethrough to receive the guidestem;

a spiral spring encircling the stem and positioned intermediate theshoulder of the plug and the spider in .a manner to normally retain theannular tapered surface of the plug in engagement with the walls of theorifice to close the same, an annular opening being formed around saidplug when the same ispressed inwardly, variable inward pressures formingvariable annular openings dependent upon the amount of the pressureexerted on the outer end of the plug.

' 2. A dispenser comprising a closure cap having a discharge opening andan internal annular shoulder, a tapered closure plug mounted in the capand projecting through the opening and having a rounded end portion anda central depending guide stem of smaller diameter than the plug forminga shoulder beneath the plug, a sheet metal spider having a central holetherethrough to receive the guide stem and radial arms to engage theannular shoulder, a spiral spring encircling the stem and positionedintermediate the shoulder of the plug and the spider in a manner tonormally retain the annular tapered surface of the plug in engagementwith the walls of the discharge opening to close the same, an annularopening being formed around said plug when the same is pressed inwardly.

3. A dispenser comprising a closure cap having a discharge opening andan internal annular shoulder, a tapered closure plug mounted in the capand projecting through the opening and having a rounded end portion and.a central depending guide stem of smaller diameter than the upper endportion forming a shoulder, a sheet metal spider having a central holetherethrough to receive the guide stem and radial yieldable arms adaptedto be sprung over the annular shoulder of the cap and to rest thereon, aspiral spring encircling the stem and positioned intermediate theshoulder of the plug and the spider in a manner to normally retain theannular tapered surface of the plugin engagement with the walls of thedischarge opening to close the same, an annular opening being .formedaround said plug when the same is pressed inwardly.
